Description

TECHNICAL FIELD

[0002] Train bulk material transportation unloading is a complex process involving various equipment and processes, the main purpose is to efficiently and safely unload bulk goods from the train car and transfer to the designated location. Common train bulk unloading methods include: car dumper unloading, spiral unloading machine unloading, chain bucket unloading machine unloading, bottom door self-unloading car unloading and automatic material taking device unloading. Among them, the car dumper is a device specially used for overturning railway open cars to achieve automatic unloading of bulk materials. The car dumper rotates or tilts the car to make bulk materials (such as coal, ore, etc.) automatically pour into the receiving hopper or conveyor below by gravity. This method has the advantages of fast unloading speed and high automation, and is suitable for rapid unloading of large quantities of bulk materials.

[0003] The steps of car dumper unloading mainly include train arrival and positioning, unloading operation and empty car dragging away. Among them, the train arrival and positioning need to use a traction locomotive to pull the vehicle to the car dumper unloading position. During the unloading operation, the car dumper needs to be manually uncoupled from other carriages, and then the car dumper starts to rotate for unloading operation. Since the position of the car dumper is fixed, the vehicle needs to be pulled each time the car dumper unloads, which results in low efficiency of car dumper unloading. In order to improve the unloading efficiency, users usually arrange multiple car dumpers on one unloading line, and multiple car dumpers work synchronously, which increases the cost of unloading equipment. At the same time, the existing train car dumper needs to pull the vehicle to be turned over to the turning table during use, and the turning table needs to be turned over with the vehicle each time, which increases the energy consumption of the car dumper during use.
